Hands-on experience building LLM-powered applications or AI agents, including tool use and multi-step workflows. Preferred Qualifications Experience designing evaluations for AI systems, including defining success criteria, building test datasets, and analyzing failures. Familiarity with LLM post-training workflows, including supervised fine-tuning, reinforcement learning, or distillation. Wondering if you’re a good fit? You love defining long-term architecture for systems at global scale. You’re curious about orchestration beyond SUNK and how to evolve it for next-generation AI.
